That is a client side implementation and you are right for Microsoft DHCP client. In the absence of a DHCP server it get mor and more "chatty" toward the end it starts to panic

No it get shorter and shorter in Microsoft land renew is a client attibute.
The renew is a client aspect. In MS land the default DHCP lease is 8 hrs so turn your PC off overnight and your lease expires. In reality it is tombstoned and it is likely you will still get the same IP anyhow.
However this is still not = "may as well be" static as this is what DHCP reservation is for. Also different devices, OS's etc may implement differently
